[clug-talk] IPCop Red interface ip address renewal

If you don't have a static IP, then you may need to tell the IPCop box to 
release/renew if/when the red interface IP changes.

I've heard of people writing simple bash scripts to periodically ping an 
external location, and when they no longer get a response from there the 
script then get's a new IP address (release./renew via dhcpclient, or 
whatever tool IPCop is using...)  So, scripts like this should be available 
online, or there might be an addon for this type of thing.

But note that while you are disrupting your connection for a moment when you 
need to get a new IP, you do not have to reboot the box.  But that's usually 
the easiest way to explain/trigger the process for someone who isn't 
technically oriented....

My thoughts...
